In this state, the device can either write data
to the memory card or read data on the card.

If the LED lights up, however, this does not
indicate that the device is accessing the
card!

The memory card is inserted.
However, the device cannot read data on the
memory card.
Possible causes:
•
The memory card does not contain any data
•
The content is not readable
•
The memory card is defective

1)
A function is started with SOPAS ET which
requires a memory card for writing. However, the
memory card is not connected.

Prerequisite: In SOPAS ET, the “SD card required” function has been activated under the
“Service” user level.

Warm-up phase of the device:
•
RFU620-101xx
: The internal temperature of
the device is between -40 °C and -20 °C.
The device starts up regular operation after a
maximum of 5 min
•
RFU620-104xx/-105xx:
The internal temper‐
ature of the device is between -25 °C and
-20 °C. The device starts regular operation
again after about 1 min.
3.3 Memory card (optional accessory)
The device can execute the following functions on the plug-in microSD memory
card:
•
Cloning function: If a MicroSD memory card is present, the device automati‐
cally saves its internal parameter set on the memory card as well. This pro‐
cedure is carried out in the framework of the recommended storing concept
for the device parameter sets. Storing the internal parameter set with the
“permanent” option triggers the cloning function. The function is used,
among other things, to conveniently transfer the parameter set to an
replacement device of the same type in the event of a fault.
•
Data logging: The device continuously records read diagnosis data after the
first manual start, e.g. via SOPAS ET. If the function is permanently set, the
device automatically resumes recording after a restart.
•
Alternatively, with 4Dpro sensors (RFU620-101xx and RFU620-104xx), the
optional CMC600 parameter memory module can also be used as an exter‐
nal storage medium for the cloning function. The parameter memory module
can be used in the optional connection module, e.g. CDB620 or
CDM420-0001. If the device is connected to a data bus via the bus connec‐
tion module CDF600-2xxx, an external storage medium is also available.
NOTE
Recommendation:
Use an empty memory card to save a parameter set for the first time. If nec‐
essary, check the contents of the card on the computer using a card reader
and delete if necessary.
The microSD memory card is not included in the scope of delivery.
Only use types approved by SICK to ensure reliable function of the memory card,
see
. The memory card has no write protection that can be
activated.
